+/**
+ * This interface is supposed to abstract the handling of room state for several
+ * fragments that can display and manipulate it. The purpose of this is to allow
+ * using these fragments both for setting up networked and local games, despite
+ * the fact that for local games the settings can be changed immediately in
+ * memory, while they have to be sent out to the server for networked games.
+ * 
+ * If/when the state changes as result of calling one of the "changeX" or
+ * "requestX" functions, that will also trigger the corresponding change
+ * listener method. There is no guarantee that calling a changeX method will
+ * actually change the setting (e.g. if you're not room chief).
+ * 
+ * For local games, getChiefStatus is always true.
+ * 
+ * Implementations of this interface are probably not thread safe and should
+ * only be used on the UI thread.
